Hi Maygen If you've read any of the really old threads, you'll find me being VERY dopey about things like f-stops (sh'dup, Ry!) and other techie things, coz I had a point-&-shoot digital. Lately, however, I've been forced to learn coz I've got a 1/2 decent digi with manual features and want to know how to use them. So, I've hit my local library and started reading a bit, and got to admit while they are a little out-dated, I've found John Hedgecoe's books to be a big help. Quite a good laugh at 70's fashions, too! There are also a couple of others too, but as I'm in the loft I'll post what they are tomorrow - climbing down ladders at 01:00 isn't my strong point, never mind clambering back up!!! Hope this helps (",) H
